What would produce better images on a D700?
-Nikon 80-200 f2.8 AF-D with a Kenko 1.4x teleconverter (equiv. of 112-280mm)
-Nikon 70-300 VR
-Tokina 80-400 (can't afford and really don't want the Nikon version)
I mostly need the 200-400 end, and I'm shooting outdoors during the day. I already own the 80-200 which is a very good quality lens, but I need more zoom. I'm also considering using the DX crop mode. My budget is $500 max.
